I noticed a bright light on the northern horizon over Lac de la Sucrerie (46 degrees 07 minutes 00.23seconds North, 74 degrees 54 minutes 11.88 seconds West) that I thought was a star, however it started to get brighter and bigger after a few minutes of staying still. After a few more minutes the “star” began to lower and fluctuate in intensity. This is when I realized it was a UFO. As it got closer I could see a red and greenish glow under the object, which by now was moving slightly erratically left to right, up and down. At this point it was in front of the mountain, about 50 feet above the lake, and about 1 kilometer in front of me. It just stayed there, silently hovering above the lake for a couple of minutes, and then slowly rose back into the sky, and further behind and above the mountain until it was looking once again like a bright star, like venus looks like. The light grew with intensity, and then faded. This happened a few times until it disappeared. About half an hour later, I went back outside to see if it was there, but it wasn't, however, after a minute of looking around in the sky I felt a sort of vibration that vibrated the whole cottage, and even the ground, (kind of like an earthquake, but more of a vibration than a shaking), which was followed immediately by a sound high overhead like a fighter jet would make, but not quite as loud. Unfortunately I did not have my video camera because I forgot it at home! It would have been one of the best UFO videos ever! I’m so sorry I forgot it!
